In Sweden February 20, 1942 1 Claim.

In the use of snow hoop rings made of metallic tubes there may, as connections between the ring and the snow hoop straps, suitably be employed stirrup shaped fittings, applied to the ring and by means of their legs clasped to the strap ends. The positions of the fittings on the snow hoop ring may in asimple manner be fixed by means of centre punch marks, but it has been found that such a fixing is not surficiently reliable. After use during sometime it may occur that the fittings are displaced laterally with the accompanying risk that the snow hoop does not function in the right way. The fixation of the fittings may, of course, also be effected in such a manner that they are riveted to the ring, in this case, however, a butt joint will be formed, whereby the movements of the snow hoop in the direction of the ski stick are rendered more difficult and the snow hoop ring is subjected to torsionwiththe accompanying risk that the seam of the ring will be damaged. Moreover, the riveting is comparatively circumstantial and somewhat disfiguring.

According to the present invention, the fixation of the fitting is rendered possible in a simple and yet quite satisfactory manner by that in the fittings there are stamped out lugs or the like, which are intended to be introduced into open ings provided in the snow hoop ring. This realization admits of a certain rotary movability of the fittings but prevents their lateral displacement along the ring.

The invention is illustrated on the accompanying drawing. Figure 1 shows a plan view of a snow. hoop ring. -Figure 2 shows a fitting developed in the plane. Figure 3 shows the finished fitting in section as viewed from the edge.

side. is 8 millimetres and the wall thickness of which If a ring is used, the diameter of which is 0.4 millimetre, the openings-preferably pos- Fig. 4 shows the finished fitting as viewed from above.

The snow hoop ring I is, as mentioned above, provided with openings 2 positioned at those places where the fittings are to be applied. The

openings arepreferably established by that four holes are simultaneously bored from one side of the ring. The boring is not effected right across the ring but only in the material on said ring sess a diameter of about 3.5 millimetres.

The fittings are formed of small pieces 3 of sheet metal stamped out approximately with the shape shown in Figure 2. In connection with the stamping out there are also provided holes 4 for the rivet or the like, by means of which the fitting is attached to the snow hoop strap, aswell as a centrally located lug 5 bent somewhat outwards. If the snow hoop ring has the dimensions indicated above, the.lug is given a length of about 5 millimetres and a width of 3 millimetres. The sheet metal pieces 3 are bent in such a manner as to obtain the shape shown in Figure 3, whereupon the fitting is ready for being mounted. In assembling, the fittings are put into their places, as shown in dot and dash lines at a place located to the left in Figure l, where also the snow hoop straps 6 are partially indicated. To this end the lug 5 is introduced into the corresponding opening 2, whereby the above mentioned fixation of the fittings is obtained. When the snow hoop ring is applied to the ski stick, the ring side provided with the openings 2 is preferably turned downwards, so that water possibly entering into the snow hoop ring easily fiows out of the same. The risk of 'snow penetrating through the small openings is extremely small.

I claim:

In an arrangement for fixing the position of the strap fittings on a ring appertaining to the snow hoop of a ski stick and made of a metallic tube, said strap fittings having the shape of stirrups which clasp the ring and by means of their legs are fastened to the strap ends, the combination of lugs stamped out in the fittings and introduced into openings in the snow hoop ring and arranged for such a cooperation with said openings that the fittings obtain a certain rotary movability considered in the direction of the stick but are prevented from lateral displace- NILS JACOB GHLE.
